SWANSON, OF CRANSTON, RHODE ISLAND, ASSIGNOR TO UNIVERSAL WIND- ING COMPANY OF BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS SUPPLY-HOLDER Application llled November 5, 1930. Serial No. 493,801.

This invention relates to supply-holders for winding machines and like apparatus and. consists particularly in improved.

means for supplying yarn, thread or other strand material to the winding or other operation.

In the following specification and claims the term yarn is used in a generic sense to indicate all kinds of filaments or strand materials, whether textile or otherwise, the term bobbin to indicate any type of supply cop, and the term package is employed to designate the product of the machine whatever form it may take.

One object of the present invention is to rovide means for holding a bobbin or other orm of supply in position to deliver the yarn to the package being wound with a sufficient length of free yarn between the bobbin and the package in accordance with certain requirements, while permitting the location of the bobbin adjacent the winding mechanism and the package being wound to afford greater convenience in placing and dofiing the supply and in piecing up the end therefrom.

Another object of the invention is to provide a supply-holder having means for receiving a fresh bobbin and carrying it into delivering position and for simultaneously dofling the spent bobbin at the same operation.

Another object of the invention is to provide a supply-holder having means for automatically gripping the bobbin as the latter is carried into delivering position and for automatically releasing the spent bobbin to cause it to be doifed from the holder.

Another object of the invention is to provide a supply-holder'wherein the spent bobbin is automatically dofli'ed and the fresh bobbin simultaneously gripped or locked to the holder by the single operation of placing the bobbin in delivering position.

Another object of the invention is to provide a supply-holder having means for gripping bobbins of various types and sizes either on the outside or the inside of the bobbin-tube or yarn-carrier.

Further objects of the improvement are set forth in the following specification which describes a preferred form of construction of the invention, by way of example, with several modifications in the means for gripping or holding the supply-bobbin.

In practically all types of winding machines and like apparatus for transferring yarn in the various processes of the textile art the supply of yarn, whether in the form of a bobbin, spool or other body or mass, must be located relatively remote from the package being wound. That is to say, it is of advantage, in some cases quite necessary, to have a considerable length of free yarn between the bobbin is located remote from the winding mechanism or the package being wound, however, it is inconvenient of access to the operator Who is required to stoop and reach to piece up the ends or to doil' and replenish the supply.

To overcome this inconvenience and handicap in the operation of winding machines or other apparatus the present invention contemplates locating the supply-bobbin at substantially the same height and closely adjacent the package being wound so that the operator in attending the machine has both the supply and the product close at hand to obviate the necessity for stooping or reaching during the several operations of doffing a spent bobbin, placing a fresh supply and connecting it to the package being wound.

The accompanying drawings illustrate a winding machine of the type shown and described in U. S. Letters Patent No. 1,749,355, granted March 4, 1930, to F.-A. Reece, but it is to be understood that the present invention is applicable to different types of winders and may be employed to advantage with other machines or apparatus used for the transfer of yarn or like material from one process to another in the textile and related arts.

Referring to the present drawings, the winding mechanism herein illustrated by way of example may be one of a plurality of similar heads or units mounted on a horizontal bed or table 2 which is supported from standards or legs 3. Rising from the bed or table 2 are brackets or frame-members 4 carrying bearings for the rotating drive-shaft 5 and other parts of the winding mechanism. As herein shown, the horizontal drive-shaft 5 is journaled in ball-bearings 6 on the brackets at and extends throughout the length of the gang machine to provide a drive for all of the several units thereof. The shaft 5 carries a series of drums or drive-rolls 7, only one of which is shown herein, a separate roll being provided for each winding unit.

The drive-roll 7 constitutes the means for rotating the package by direct contact with the periphery of the yarn mass and, in accordance with the invention of the Reece patent hereinbefore referred to, the roll 7 embodies means for traversing the yarn longitudinally of the package to deposit it in helical coils which form the layers building up the yarn mass. For this purpose the roll 7, which for convenience may be termed a traverse-roll, is provided on its peripheral surface with a yarn receiving and guiding oove 8 consisting of crossing and connectmg helices extending in opposite directions. The groove 8 in the surface of the roll 7 may comprise any suitable number of turns or helices extending in one direction and then returnin in the opposite direction and crossing the rst turns and joined thereto at the end. The crossing points of the groove are lever for initiating the operation of the stopping-mechanism of the winding machine in the usual manner when the yarn breaks or its supply is exhausted.

The product of the winding machine may be a package of any preferred form such as cylindrical or conical. The yarn may be wound on any suitable receiver or core such as a paper tube or a wooden or fiber mandrel. The present drawings illustrate the machine as adapted for winding conical packages and for this purpose a con-tube or tapered wooden receiver C is rotatably mounted on a deadspindle 10. The Winding-spindle 10 is carried at the end of a swinging arm 11 which is pivoted on a horizontal stud 12 supported 1n a. hub at the upper end of an upright 14 extending from one of the frame-members or brackets 4. The arm 11 is constructed in two parts, see Fig. 2, with an outer extension 15 arranged to swivel in a hearing at the end of the main arm to adapt the windingspindle 10 to assume an inclined position with respect to the axis of the roll 7, whereby to adapt the peripher of the receiver to make contact with the sur ace of the roll throughout its length. The wooden tube or yarnreceiver C may be held on the winding-spindie 10 by means of a latch 16 at the outer end thereof.

In machines of the present type the driveor transverse-roll is rotated continuously and the winding operation started by placing the surface of the yarn-receiver, or the periph cry of the package, as the case may be, in contact with the roll. A stopping-mechanism is usually'provided for removing the package from contact with the drive-roll when it is required to arrest the winding operation upon breakage of the yarn, exhaustion of its supply, or at the completion of the package. The stopping-mechanism and the means for automatically initiating its operation may be of any well-known construction, but are not herein described since they form no part of the present invention. Suffice it to state, that to start the winding the operator shifts a control lever to move the yarn-receiver G into osition to make contact with the surface 0 the drive-roll 7, while the arrestment of the winding is effected through the automatic operation of the stopping-mechanism upon failure of the supply or at the completion of the package.

Thepresent improved supply-holder for holding a bobbin, cop or other type of supply is arranged at the front of the machine and, conveniently, it may be supported from a horizontal rod 17 mounted at the end of arms or brackets 18 clamped to the legs 3 of the machine. As herein shown, the brackets 18 are clamped to the web of the legs 3 by means of bolts 19. The supply-holder proper is mounted on an upright bracket 20 having a hub 21 surrounding the rod 17 and clamped thereto by means of set-screws 22-. As shown in Fig. 2, the upright portion 23 of the bracket 20 is set at a slight angle to the vertical and its position may be varied by adjusting its hub 21 on the rod 17.

Attached to the lower part-of the u right 23 of the bracket 20 is a tension-brac ct 25 secured in place by bolts 26. The tensionbracket 25 comprises a curved arm extending laterally from the side of the bracket 20 and having a depending portion 27 on which the tension-device is mounted. As shown most clearly in Fig. 1, the tension-bracket 25 is made in two sections, one half being constituted by the depending portion 27 and the other half being a complementary section 30 fastened to the main part at the top by a screw 31. A cross-pin or rivet 32 extendsbetween the two halves of the tension-bracket 25 and may carry a roller or porcelain guide 33 under which the yarn y is adapted to feed. The lower portions of the two parts of the tension-device are of substantially lenticular outline, as shown in Fig. 2, with their pointed ends flaring outwardly from the opening between the parts to form a reentrant guideway which facilitates the threading of the yarn thereinto. The opposite sides of the two halves of the tension-bracket 25 are spaced at a slight distance apart, and arranged in line with the slit or opening therebetween are two opposite tension-disks 34 and 35. The tension-disks 34 and 35 are mounted on a slidable cross-pin 36 extending through a hub 37 on the section 30 of the bracket and a hole in the side of the main bracket. The pin 36 is formed at one end with a head 38 abutting the end of a helical spring 40 which bears against the left-hand tension-disk 35. An L-shaped lever 41 is pivoted at 42 to the side of the bracket 25 to adapt it to bear against the head 38 of the pin 36, and a series of weights 43 carried on a spindle 44 rising from the lever causes the latter to slide the pin 36 in its bearings whereby to create pressure tending to force the disk 35 toward the disk 34. As the yarn y draws between the two disks 34 and 35 the latter are pressed against the strand to resist its draft and apply tension thereto.

Secured to the tension-bracket 25 above the tension-device is a slub-catcher 45 of any suitable construction; herein illustrated as comprising a pair of opposite plates or blades 46 and 47 arranged with a slit or opening between their edges through which the yarn stitutes the main support for the supplyholder, indicated generally at52. The arm 51 is constructed with a plate-like portion 53 having finished faces 54 adapted to seat against the forward face of the upright 23 of the bracket 20. In. the upright 23 is a vertical slot 55 adapted to receive bolts 56 projecting through the lower portion of the arm 51, with nuts 57 for clamping the arm. in position. By releasing the nuts 57 the arm 51 may be adjusted vertically on the bracket 20 to varythe position of the supply-holder and the bobbin carried thereon in accordance with the length of the latter. As shown in the present drawings the supply-bobbin B is mounted in substantially vertical position on the supply-holder with its nose end pointing downwardly and in close association with the guide 48 through which the yarn 3 draws.

The bobbin B is held on one or the other of a pair of stub-spindles 60 and 61 radiating from a rotatable hub 62 journaled on a stud 63 fastened in a hub or boss 64 at the upper end of the arm or bracket 51. Referring to Fig. 5, the stud 63 has a reduced portion held in a bore in the boss 64 on the arm 51 and the hub 62 is journaled on the enlarged projecting portion of the stud abutting the face of the boss 64. A collar 65 is secured to the outer end of the stud 63 by 61 have reduced threaded portions 67 screwing into radial holes in bosses 59 on the periphery of the hub 62 and their outer ends are rounded to provide for easy insertion into the bores of the bobbin-tubes or yarn-carriers b.

Referring to Fig. 4 of the drawings, a plunger-pin 68is held in atransversebore 69in the hub 62 and urged outwardly from the side of the hub by a spring 70 pocketed in the bore. The end of the plunger-pin 68 is pointed or beveled off on the sides to adapt it to snap into one of a plurality of V-shaped notches 71 and 72, see also Fig. 5, cut into the side of the fixed collar 65. The plunger-pin 68 and the notches 71 and 72 are so related that when the hub 62 is rotated theplunger acts as a detent therefor to hold the two opposite spindles 60 and 61 in vertical position. That is to say, the hub 62 may be turned through 180 degrees to reverse the position of the spindles 60 and 61, and when thus operated the plunger-pin or detent 68 will engage one or the other of the notches 71 and 72 to retain the hub in the position to which it is adjusted.

The improved supply-holder is arranged to be operated by placing a bobbin on the spindle projecting upwardly from the hub 62 and then turning the spindle down into position to point toward the guide 48 and the tension-device therebcncath. This operation may be performed with practically one movement of the hand and as the bobbin is turned down into delivering position it is locked in place on the spindle by means of an automatically-operated latchingor gripping-device which may take various forms.

As shown in Figs. 1 to 5, the automatic gripping-device is constituted by a pair of arcuate strips or ways 75 which straddle the sides of the bobbin B and engage under :ts head as shown most clearly in Fig. 5. The

two arcuate strips 75 are of the same form' and arranged concentric with the axis of the hub 62, one being secured to an arm or extension 76 projecting from the side of the hearing boss 64 and the other attached to a similar arm or extension 77 on the fixed collar As shown in Fig. 3, the arcuate strips 75 are fastened to the arms 76 and 77 by means of screws 78 passing through lateral slots 79 in the strips, see Fig. 4. Through this means of attachment the two strips 75 may be adjusted toward and away from each other to regulate the width of the opening between their opposite edges in accordance with the size or thickness of the shank of the bobbintube b. It will be observed by reference to Fig. 3 of the drawings that when a bobbin B Is placed on the upper spindle 60 with its base seated against the boss 59 on the hub 62 the shank of the bobbin-tube b will be passed between the edges of the arcuate members 75 as the bobb n is turned down into delivering position. These edges of the members 75 will therefore be caused to engage under the head 6 of the bobbin-tube b as the bobbin B is turned down into vertical position whereby to serve as a support or rest to hold the bobbin from dropping off from the spindle 60; the method of operation of the device heir-g as hereinafter more fully explained.

Figsf6 to 8 of the drawings illus'rate a modified form of construction of the latchingor gripping-means for the bobbin wherein a latch is prov'ded for engaging the interior of the bore of the bobbin-tube 15. Referring to these views, the bobbin-spindles 80 and 81 are arranged in offset relation with respect io the axis of the rotatable hub 82 on the stud 83. As shown in Fig. 8, the hub 82 has ofi'rct portions 84 and 85 bored to receive the sp'ndles 80 and 81 which are driven into the bores or otherwise suitably secured in place. Each of the spindles 80 and 81 is formed wi h a longitudinally-extending slit or slot 86, in which is pocketed a rockable latch 87. Each latch 87 is pivoted on a cross-pin 88 and its device as having a tapered butt end instead of a straight barrel with a head at is base. This form of tube is used with certain types of spinning or twisting frames.

The opposite arm of the latch 87 terminates in a curved portion 92 which 'is rounded off to adapt it to bear against the periphery of the stud 83. The stud 83 is formed with a peripheral groove 93 which extends throughout substantially 180 degrees of its circumference, thus providing a sort of eccentric camface having rises 94 at its ends which rock the latches 87 as their curved ends 92 ride up out of the groove. The purpose of this construction is to provide-that as each of the spindles 80 or 81 is swung downwardly to bring the bobbin into delivering position its respective latch 87 will be rocked to engage its pointed end 90 in back of the thimble 91 in the bore of the tube t to hold the bobbin in place; while on the other hand, as the opposite spindle is turned upwardly the curved end of the latch will ride into the groove 93 in the stud 83 to, release its hooked end from the bobbin-tube so that the latter may drop off from the spindle to be automatically dofled in the manner illustrated in Fig. 8. The hub 82 carries a slidable plunger-pin 73 engageable with notches 74 in the fixed collar 95 on the endof the stud 83 and operating to detain the hub in the position to which it is turned to locate the bobbin B in delivering position. I

In Figs. 9, 10 and 11 of the drawings a. still further modification of the latching-device is illustrated. \Vith this latter form of construction a hub 96 is journaled on a stud 97 held in a boss 64 at the upper end of the arm 51, the stud having a head 98 for retaining the hub in place on its bearing. Projecting radially from the hub 96 are diametrically-opposed bobbin-spindles 99 and 100, each of which is bored axially at 101 with an enlarged countei'bore 102 at its inner end. Slidable in the bore 101 of each spindle is a plunger 103 having an enlarged head 104 slidable in the counterbore 102. The head 104 is provided with a pointed or beveled end adapted to engage in a V-shaped notch or groove 105 on the bottom of the stud 97. A coiled spring 106 is pocketed in the counterbore 102 at the rear of the head 104 on the plunger 103, tending to hold the pointed end of the plunger bearing against the periphery of the stud 97 and. forcing it into the notch 105 when the spindle is turned into down position as shown in Fig. 10.

tending diametrical y of the spindle 99 or.

100, as the case maybe, with their pointed ends 112bearing against the side of the bore. When the plunger 103 is slid to engage the 7 pointed end of its head 104 with the notch 105 on the underside of the stud-97 it will act to rock the dogs 110 outwardly to cause their ends to engage behind the ends of the tubular thimble 91 in the bore of the bobbintube t, see Fig. 10. In operating the modified form of device illustrated in Figs. 9, 10 and 11 of the drawings it is necessary that the operator hold the bobbin in place on the spindle until it has reached its inverted position, whereupon the plunger 103 is caused to rock the dogs 110 outwardly to engage them with the bobbin in the manner as above explained; but as the spindle is turned away from its lowermost position, as indicated in Fig. 11, the plunger 103 is forced outwardly against the pressure of its spring 106 whereby the dogs 110 are actuated to withdraw them from engagement with the interior of the bore of the bobbin-tube t.

The method of operation of the present improved supply-holder as embodied in its various forms of construction will next be explained in connection wth the operation of the winding machine as a whole. The winding machine is prepared for operation by placing a cop-tube or yarn-receiver C on the dead-spindle 10 and securing it in place by means of the latch 16. A supply-cop or bobbin B is placed on the supply-holder in position to deliver its end tothe winding, and with the device illustrated in Figs. 1 to 5 the method of applying the bobbin to the holder is as next exp alned. Assuming that the hub 62 is in position with the bobbin-spindle 60 projecting upwardly, the operator grasps the bobbin B and places it on the spindle in the manner indicated by the dash lines in Fig. 3. Practically with the same motion of the hand the bobbin is swung to the'right, or clockwise as viewed in Fig. 3, and this movement continued to carry it down into inverted position as further indicated by dash lines in Fig. 3. During this clockwise turning of the bobbin B under the rotation of the hub 62 the head I) of the tube B will ride inside of "the two opposite ways or strips 75 with the shank of the bobbin passing between the edges of the strips. As the hub 62 is turned to the position shown in Figs. 1 and 2 to bring the bobbin B into delivering position the plunger-pin 68 engages with the notch 72 in the side of the collar 65 to restrain the hub from further turning movement. The bobbin B will thus be held in inverted position with its nose or delivery end adjacent the wire guide 48 through which the yarn 3 leads to the tension-device. It has been noted that the arm 51 on which the suppl -holder is mounted may be raised or lowere 011' the bracket or' standard 20 to properly locate the delivery end of the bobbin with respect to the guide 48, whatever the length of the bobbin may be.

With the bobbin B in delivering position the end of the yarn y is led down through the guide 48, thence through the slub-catcher 45' and drawn into the re-entrant opening at the bottom of the tension-bracket to enter it between the opposed faces of the tension-disks 34and 35. The yarn is then led from the tension-disks around the guide-roller 33 and thence drawn up to the thread-bail 9 and across the periphery of the traverse-roll 7.

v The end of the yarn is suitably secured to the cop-tube or yarn-receiver C and the machineis ready for operation.

The winding operation is started by shifting the starting-handle or control-lever to carry the surface of the cop-tube C down into contact with the periphery of the driveor traverse-roll 7 and as this contact is effected the cop-tube will be rotated from the roll to wind on the yarn; Immediately the coptube C starts to rotate the yarn leading thereto across the periphery of the traverse-' roll 7 will enter the groove 8 in the surface of the roll to be traversed thereby from end to end of the cop-tube. Under this action the yarn is traversed back and forth to deposit it on the cop-tube C in helical coils which iorm the layers of the package P shown in %Vhen the supply of yarn in the first bobbin is exhausted the winding is arrested by the operation of the automatic stopping-mechanism, previously mentioned, and the operator supplies a fresh bobbin in place of the spent one. To replenish the supply the operator has only to place a fresh bobbin B on the spindle 61 which isthen in uppermost position and to turn the bobbin down into delivering position. As the fresh bobbin B is turned to the right, as viewed in Fig. 3, the tube t of the spent bobbin is moved to the left to slide its head I) OH from the ends of the ways 75, whereby the empty tube is released to permit it to drop down Into a bobbin box or other suitable receptacle; it being noted that the bobbin-tube is released outwardly beyond its delivery position so that as it drops it will not strike against the yarnguide and tension-device. It will thus be seen that the doffing operation is performed automatically, simultaneously with the placing of a fresh bobbin in delivering position, and consequently this work may be accomplished much more conveniently and expeditiously whereby to increase the productive capacity of the whole machine. After a fresh bobbin is in delivering position the end of the yarn therefrom is threaded into place in the manner as previously explained and. the machine is started again, only a slight interval being required for replenishing the supplyduring the arrestment of the winding operation.

It is to' be particularly noted that the bobbin is supported in elevated position at v the front of the winding-mechanism within easy reach of the operator. By inverting the bobbin from its usual position on the supply holder the yarn is caused to feed 1 down through the tension-device and then up to the traverse-roll 7 with'a considerable length of free yarn between itspoint of delivery and'the point where it delivers to the package. This relatively long length of yarn is of advantage-in reducing the angle at which the yarn leads to the traverse-roll at the ends of its traverse thereby. In other words, the

' yarn leading from its delivery point to the traverse-roll does not make a sharp angle with the axis of the roll as it is traversed to; 'theends of the package so that it has no tendency tolift out of the guidln groove 8.

Moreover, a considerable length 0 free yarn between the delivery-point and the package is of advantage in order that whenever the strand breaks at, or in advance of, the tension-device, the broken end will not run into placed on the spindle projecting upwardly from the hub 82 and swung down into the position shown in Figs. 6 and '7. As the hub 82 is rotated on the stud 83 the rounded end 92 of the latch 87'will be caused to ride up out of the groove 93 in the stud to rock the latch to engage its pointed end 90 in back of the end of the interior sleeve or thimble 91 in the bore of the bobbin-tube 25, see Fig. 7, whereby to secure the bobbin in place. When the yarn on the delivering bobbin has been exhausted a fresh bobbin is placed. on the uppermost spindle 80 and the latter swung m a clockwise direction as indicated' in Fig. 8. The latch 87 in the spindle 80 isthereupon immediately engaged with the end of the thimble 91 in the bobbin-tube t in the manner as before explained. Meanwhile,

, as the fresh bobbin B is being turned down into delivering position, the spindle 81 carrying the tube ofthe spent bobbin is swung to the left whereby the curved end of its latch 87 is caused to enter the groove 93 in the periphery of the stud 83 so that the lower hooked end 90 of the latch is released from the thimble 91 in the empty tube It. The empty tube is therefore immediately released so that it will drop off from the spindle 81 to effect automatic dofling thereof.

The modified form of device illustrated in Figs. 9, 10 and 11 operates in substantially the same manner as above explained. When a bobbin B is placed on the uppermost spindle and swung down into delivering position, as shown in Figs. 9 and 10, thespring 106 acts on the plunger 103 to engage its pointed end with the notch 105 on the underside of the stud 97. The sliding action of the plunger 103 rocks the dogs 110 to cause their ends to engage in back of the end of the interior thimble 91 in the bobbin-tube t to thereby latch the bobbin in place on the spindle 100. When a fresh bobbin is placed on the uppermost spindle 99 and the hub 96 again rotated to carry this bobbin into de- 0 livering position the tube 25 of the spent bobbin is released in the manner as illustrated in Fig; 11. That is, the pointed end of the head 104 of the plunger 103 will be caused to rise outof the notch 105'inthe stud 97 to force the plunger downwardly against the action of its spring 106, whereupon the dogs 110 will be withdrawn into the lateral bore 111 in the spindle 100 to retract them from engagement with the end of the'thimble 91 in placing the supply or in threading up the yarn therefrom to the winding mechanism. The operator has only to draw the yarn from the nose of the bobbin down through the guiding-device and tension-device and then up to the package being wound, this operation being accomplished without reaching or stooping and with a relatively short movement of the hand. At the same time a considerable length of free yarn is provided betweenv the bobbin and the point at which it is taken up by the windingto insure the desired advantages as above pointed out.

It is further to be noted that the present improved supply-holder, in each of the various forms illustrated, provides for greater convenience and facility in replenishing the supply' and piecing up the end; the dotting of the spent bobbins being performed automatically without any attention on the part of the operator. The operator has only to place a fresh bobbin on the holder and swing it into delivering position, whereupon it is automatically seized and locked in place and in the meantime the'tube from the spent bobbin is automatically dofi'ed and discharged out of the way.

Through this improved arrangement and 1 increases the productive capacity of the whole machine, prevents fatigue on the part of the operator and consequently has a tendency to improve the quality of the product. T'hepresent'invention is therefore of great advantage in the textile art, being adaptable for use with various types of machines and apparatus other than the winding machine herein shown. I

While the improved device is herein illustrated and described in a preferred form of construction with two modifications in the details thereof, it is to be understood that other changes may be made in the structure and relation of the parts without departing from the spirit or scope of the invention.
